Scatterometry – Measuring Ever-Smaller Chip Production

Corry Micronics 90º high power hybrids cover a frequency range from 870 MHz to 2,200 MHz. A 90º hybrid has two outputs that maintain the same output level but the signals on the two outputs are 90º apart. On our hybrids there is a fourth termination or isolation port that absorbs half of any reflected signals from any mismatch on either output...
